微动开关，顾名思义，使用很微小的力度的开关。其触电间距较小，力矩较大。一般外部有驱动杆。在尺寸上有小型，超小型，超级小型等。功能上则有防水型。最常见的应用就是鼠标按键了。
1.小型微动开关：
一般尺寸为长27.8宽10.3高15.9，参数方面又高容量，低负载等不同变化。如v3系列：
operatingfrequency (mechanical).....120 operations / mim
operatingfrequency (electrical).....all ratings-10~30 operations /mim
contactresistance (initial).....30m ω (max.)
insulationresistance (at 500vdc).....100m ω (min.)
dielectricstrength (50-60hz).....1000vac rms
servicelife(mechanical).....min. 5000000 operations
servicelife(electrical).....min. 10000 operations
2.超小型微动开关
一般尺寸为长19.8宽6.4高10.2，功能上有高精度和高寿命的不同性能。如sm系列：
operatingfrequency (mechanical).....120 operations / mim
operatingfrequency (electrical).....10~30 operations / mim
contactresistance (initial).....300m ω (max.)
insulationresistance (at 500vdc).....100m ω (min.)
dielectricstrength (50-60hz).....1000vac rms
servicelife(mechanical).....min. 10000000 operations
servicelife(electrical).....min. 6000 operations
3.超级小型微动开关
一般尺寸为长12.8宽5.8高6.5，这一型中又有特薄型的设计。如df系列
operatingfrequency (mechanical).....120 operations / mim
operatingfrequency (electrical).....0.1a-120,3a-10~30 operations /mim
contactresistance (initial).....100m ω (max.)
insulationresistance (at 500vdc).....100m ω (min.)
dielectricstrength (50-60hz).....1000vac rms
servicelife(mechanical).....min. 1000000 operations
servicelife(electrical).....3a-min. 10000 operations
4. 防水型
此类产品其防水级别已达到ip67，如sw系列：
operatingfrequency (mechanical).....120 operations / mim
operatingfrequency (electrical).....10~30 operations / mim
contactresistance (initial).....30m ω (max.)
insulationresistance (at 500vdc).....100m ω (min.)
dielectricstrength (50-60hz).....1000vac rms
servicelife(mechanical).....min. 2000000 operations
servicelife(electrical).....min. 10000 operations
